Looking deeper. This function actually cannot be called from this
context. It does:

          irq_get_desc_buslock(irq, &flags, 0);

which means for any interrupt which has an actual buslock implementation
it will end up in a sleepable function and deadlock in the worst case.

Marc?

I will wait for Marc's response regarding this issue.
Regardless, if any changes are required, I believe it would be better
to address them in a separate patch, as this behavior existed before my
modification.

Correct.
